EMBELLISHING WOOD.

SPECIFICATION forming part of Letters Patent No. 443,447, dated December23, 1890. Application filed September 20, 1889. Serial No. 324,557. (Nomodel.)

To all whom it may concern: I

Be it known that we, SILAs M. LAND and SAMUEL A. V AN BUSKIRK, both ofFort Scott, in the county of Bourbon and State of Kansas, have inventeda certain new and useful Process of Embellishing \Vood, of which thefollowing is afull, clear, and exact description, reference being had tothe accompanying drawings, in which means for carrying out our processis shown.

Our invention consists in a process, liereinafter described, by which adesign of any desired configuration may be transferred to the wood andthen reduced to a smooth and finished condition.

lVe will now proceed to describe one of the ways by which our improvedprocess may be carried out.

Figure I is a vertical longitudinal section of a machine for carryingout our process. Fig. II is a perspective View of the same. Fig. III isa perspective view of the embellished wood, showing a portion of thesame in a finished condition and a portion in an unfinished condition.

Referring to the drawings, l represents the supporting-frame of themachine, on the top of which is a table 2, over which the materialpasses as it is being embellished.

3 represents a corrugated feed-roll, which is journaled in the frame 1in the proper position, so that its corrugations may extend up throughan opening 4.111 the table a slight distance above the plane of thetable in order that it may engage the material being embellished andforce it along through the machine.

5 6 7 8 represent a train of gear-wheels connectin g the feed-roll 3with the power-shaft 9.

10 represents a pulley on the power-shaft, which may be driven by a band11.

12 represents an additional pulley on the power-shaft 9, said pulleybeing connected by a band 13 with a pulley 14 on a shaft 15. The shaft15 is supported by a frame 16. On the shaft 15 is an additional pulley17, which is connected by a band 18 with a pulley 19 on a planer-shaft20.

21 represents a U-shaped frame, in which works a screw 22, having ahand-wheel 2d 011 its upper end. Secured to the lower end of the screw22 is a vertically-sliding frame 24. Secured to the lower side of theframe 2% by straps 25 is a hollow impression roll or die 20. Saidimpression-roll may be heated by a gas or other jet 27, located therein,the jet being supplied by a pipe 28.

29 represents aframe, which may be hinged to the frame 21 at 30.

31 represents a screw working in the frame 29, on the upper end of whichis a hand-wheel 32, and on the lower end of which is secured avertically-sliding frame 33. To the frame 33 is secured by straps 3a theplaner-shaft 20, on which the planing-knives 35 are situated. The frame29 may be secured to table by bolts 36, or the bolts may be removed andthe frame and planer turned back on its pivot 30, when so desired.

37 represents a hollow burnishing-roller supported by braces 38, whichare connected to the frame 29.

39 represents a gas-jet located in the roller 37, which may be suppliedby a pipe 40.

ll represents a roller, on which the material travels in passing throughthe machine, and which acts as a support to the matorial beneath theburnishing-roll.

42 represents a portion of the material after it has been acted upon bythe impression-roll or die, and as represents the same after it has beenacted upon by ing-roll;

The operation is as follows: lhe wood is first passed under the heateddie or impression roll 26, which may have any desired design thereon,the die of course embossing the wood to a greater or less degree,according to the depth of the design in the die and the pressure placedupon the die. For instance, if it is desired to have an impression withcertain parts of the same of a darker shade than other parts, the designon the die is made of greater or less prominence, so that when theimpression is made in the wood the portion that is to be the darkestwill be the deepest, the heat of course making the wood dark. After thewood has passed beneath the die, it then passes beneath the planer,which reduces the raised or embossed portions of the the planer andburnishwood .down to a comparatively smooth surface, and thus producinga design or figure in dark and l ght wood, wherein the shadows and otherportions intended to be dark are blending of the lights and shadows isat-' tained and governed by the extent to'which certain portions aredepressed, the darkestportions being deepest, while the medium tints arenot so deep and thehighest lights are left above the general le vel.Thus it will be seen that the planer will entirely remove thediscoloration from the prominent portions, while it only reaches andremoves the outer surface of the discoloration of the intermediateelevations, thus blending the high lights with the deep shadows in thelower depressions, into which latter the planer does not extend at all.Theplaner, however, while it is eifective in producing the proper lightsand shades andin reducingtoaconsiderable extent the prominent orelevated portions, yet it cannot, for reasons obvious, make the wholesurface of the design perfectly smooth and flat and on a level with thebackground.

Hence it is necessary for this reason and for the further purpose ofproducing a highlypolished surface to pass the board beneath ,a heatedburnishing-roller 37, which, being driven at a higher rate of speedthanthe embossing-die, simultaneously smoothes out the elevations so as toreduce them to the level of the deepest depressions and burnishes orpolishes the whole surface, producing a very artistic effect, and onewhich to remove the discoloration from the more prominent portions, andfinally smoothing out the remaining elevations so as to reduce them tothe level of the depressions, but without cutting away any of'thediscolored surfaces,

substantially as set forth.

2. The process of embellishing wood, which consists in embossing thesame with aheated die, planing 01f thesurface of the wood so as toremove the discoloration from the more prominent portions, and finallyrubbing the surface under the influence of heat until the remainingelevations are reduced to the level of the depressions and the wholesurface is burnished, substantially asset forth.

3. The process of embellishing wood, which consists in first passing thewood under a heated die and forming a design in cameo therein, which ismade darker than the other parts of the wood under the in fiuence of theheat, then cutting away the raised portions of the wood, leaving thereduced parts lighter, and finally passing the wood under the heatedburnisher, substantially as set forth.
